Aeroplane

' My invention relates to anew and useful improvement in an aeroplane, and particularly the body and wing construction thereof, as well as the mechanism for elevatingthe a aeroplane and preventing sudden downward movement thereof. 7

It is an object of the present invention to provide in an aeroplane a body construction in which a'minimum wind resistance is provided.

Another object of the invention is the provision in an aeroplane of a body construction whereby an inclined deflecting portion at the forward end thereof may be afforded.

Another object of the invention is the provision in an aeroplane construction of a plurality of movable, swingably mounted elevating members and mechanism for moving said swingably mounted members in a body to effect a lifting power on the aeroplane body when moving in one direction, and so arranged and constructed as to offer a minimum resistance when moving in the reverse direction.

Another object of the invention is the provision in an aeroplane of means for connecting a plurality bers to the motor of the engine for directing an elevating power against the body of the 30 aeroplane.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be best understood by a reference to the accompanying drawings which form a part of the specification and in which Fig. 1 is a fragmentary front elevational view of the invention.

Fig. 2 is a sectional view taken on line 2 2 of Fig. 1. V V p Fig. 3 is a fragmentary sectional view taken on line 3-.3 of Fig. 2. v

v In the drawings I have illustrated the in+ vention as provided with a body 7 having an inclined deflecting portion 8 at the forward end thereof, projecting diagonally outwardly downwardly from which are braces 10 and 9 whichserve as supports for the landing gear the portions 23, 24 and 25 to the upperrail of the frame so as to provide hub portions 26 and plates 76. cranks 31 and 32 of the crank shafts88 and of swingably mounted mem-;j.34, the cheeks 29 and extending to the armsf87 and 38 in spaced relation and conarms 37 and 38 of the yokes are double framesare at. the same elevation or same rel- "'ative location on the'same wing. 7

ing 11 and 12. The opposite wings of the aeroplane are of similar construction so that a description of one will sufiice for both.

The brace'9 is braced by the rod 13 in which'is interposed a turn buckle to the brace 14 which attaches to the undersurface of the wing 15. Extending outwardly from the upper surface of the body is abrace 16 which also serves to support the wing, and as shown in Fig. 2 the wing has a portion 17tapered 0 and secured to the body. A frame 18 extends forwardly from the tapered portion and serves as a support for a plurality of overlapping, plates 19iwhich are held sta tionary but which are sufficiently resilient und'ersupernormal strain to separate and allow the air to pass therethrough. The lower rail 20 of the frame is connected by the braces 21 and 22 to the portions '17 and 18 and by 27 which serve as bearings for crank'shafts. A frame 28 is provided in which is swingably mounted a plurality of overlapping -This frame is connected to the cranks 31 and 32. Projecting upwardly from the rod or brace 35 are yokes 36 ,havingthe nected to the rail 18. Extending through these yokes is a shaft 13 which is connected to and driven by the shaft 4 1 of the engine. Fixedly mounted on the shaft 43 between the grooved sheave wheels 39. Fixedly mounted on the crank shafts 33' and 34 between the arms of the yokes are sheave'wheels 10 which are connected by the chains 41 and 42 to the 'sheavewheels 39' or by any other suitable 98 means.
